`erly space the matrix for different dies, and

relates more particularly to the feed-control: ling mechanism of suchmachines.

The object of the improvement is to provide I means for readilychangingthe measurements of feed movementby an adjustment of partsconnected With an escapement.

The invention consists in the devices and combinations hereinafter fullydescribed, and particularly pointed out in the claims.

In the accompanying'drawings, Figure l is a plan view of the escapementmechanism of a matrix-making machine. Fig. 2y is a side I elevation ofthe same, showing the frame in section. Fig. 3 is a vertical section ofthe escape-Wheel, its supporting-sleeve, pinions, &c. Fig. 4 is a planview of the pinions and rack. Fig. 5 is a detail of the auxiliaryspring.

In said drawings, 1 designates a rack connected to a matrix-carriagethat has a springtension in the direction of the arrow e.

2 is the escapement-Wheel, mounted on a sleeve 3, that turns on a post4, which is secured to the machine-frame 5. On the sleeve 3 are pinions6, 7, and 8, held by a feather 9 from turning, and held in adjustmentvertically by set-screws lO.u The adjustability of the pinions enablesthem to be severally placed in position to be engaged by th'e rack 1.The rack is pivoted to the carriage 25, so as to permit lateral movementof the outer end, and a spring 1l, secured to post l2, bears against theback of the rack to adj ust it to the diiferent-sized pinions and holdit to engagement'with them. vTo aid the rack in turning the scape-Wheel,especially when a small pinion is being used, there is provided anauxiliary coil-spring 13,- having one end attached to the sleeve 3,andthe other to apost 14 on the machine-frame, and which tends to `first orminimum movement.

rotate the sleeve in the same direction as the rack. Over thescape-Wheel is a `lever 15, fulcrumed at 16, and carrying on `its arm 17a pawl 18 for holding the Wheel against the 55 force of the rack. Asecond lever 19, pivoted to the former at thepwheel-center, carries thepawl 20, that is normally free from the Wheelf teeth. The projecting armof Vthis lever has retreating steps 21, that are engaged by corref 6oand pins is such as to permit a movement of 4the scapewvheel equal toone tooth for the first step, two teeth for the second, three for l thethird, and so on through the series.` Thus the movements are all exactmultiples of the decrease the quantities of the matrix-carriage'feed-movements permitted by these escapement movements, thedifferent-sized interchangeable pinions 6, '7, and 8 are utilized.`

The escapement devicesare arranged to provide suitableproportionatespacings of the matrix forA dies cut on a given scale. Ifdies .of aditferent size are substituted, these escapement devices Willstill control the proportions of movement, While the substitution of 8othe appropriate pinions will afford the proper quantity .of movement.If, for illustration, dies of a given scale of sizes are adapted. to beused in connection With a feed permitted by engagement of the rack 1with the small 85 pinion 6, anda proper spacing for the difterentletters of the set is produced by the stepped lever and stops connectedWith 4the, escapement, and dies of a larger face'are then substitutedfor the former, the increased 9o` ably increase the matriiespacing forthe p* larger dies, while the proportions of measurement of spacing forthe varying `dies of the set is still regulated by the stepped lever andstops.

Patentable subject-matter disclosed herein roo and not herein claimed isreserved to be claimed in a pending application for patent To increaseor 76 l filed by me March 18, 1889, Serial No. 303,657.

What I claim, and desire to secure by Letters Patent, is-

l. The combination, with the feed-escapement in a matrix-making machine,of pinions ment, .pinions of varying sizes carried on the scape-Wheelshaft, and means for adjusting the pinions severally to the rack,substantially as set forth.

3. In a matrix-feed mechanism, an escape- 4Wheel, a pawl for controllingits movement, a

rack and pinion for turning its spindle, and an auxiliary spring foraiding the Wheel rotations, having one end attachedv to a fixed objectand the other to the Wheel-spindle, substantially as set forth.
